"reuters:  Jorge Mario Bergoglio of Argentina was elected in a surprise choice to be the new leader of the troubled Roman Catholic Church on Wednesday, and said he would take the name Francis I. Pope Francis, 76, appeared on the central balcony of St. Peter's Basilica just over an hour after white smoke poured from a chimney on the roof of the Sistine Chapel to signal he had been chosen to lead the world's 1.2 billion Roman Catholics. The choice of Bergoglio was announced by French cardinal Jean-Louis Tauran with the Latin words ""Annuntio vobis gaudium magnum. Habemus Papam"" (""I announce to you a great joy. We have a pope"" READ ON: Argentina's Bergoglio elected as new pope  Habemus Papam! We have a new pope. I'm no devout Catholic but somehow every time a new pope is elected, my hope for an even more open, relatable Church is renewed. That is notwithstanding his historically conservative beliefs."
